Ken Clarke: Pro-Europeans must organise themselves

If the people of the UK left the EU, Kenneth Clarke MP says he believes we would "run the risk of pulling ourselves off into isolation".

"Membership of the EU is essential if we're to have a proper voice in world affairs," the former Conservative cabinet minister told the BBC's Andrew Marr programme.

He referred to the current debate on the issue as "silly" and stressed the need for pro-Europeans to "organise themselves properly".
